如何使用Spring Data R2DBC和Postgres将字段保存为JSON

// 实体类
@Table("my_table")
public class MyEntity {
    @Id
    private Long id;

    @Column("data")
    @Type(type = "json")
    private String jsonData;

    // 省略getter和setter方法
}

// Repository接口
public interface MyRepository extends ReactiveCrudRepository<MyEntity, Long> {
}

// 业务逻辑层
@Service
public class MyService {
    private final MyRepository myRepository;

    public MyService(MyRepository myRepository) {
        this.myRepository = myRepository;
    }

    public Mono<MyEntity> saveData(String jsonData) {
        MyEntity entity = new MyEntity();
        entity.setJsonData(jsonData);
        return myRepository.save(entity);
    }

    public Flux<MyEntity> getAllData() {
        return myRepository.findAll();
    }

    // 其他操作方法...
}
